REFRIGERATOR.

Specification of Letters Patent.

Patented Aug. 3, 1915.

Application filed June 23, 1914. Serial No. 846,717.

To all whom it may concern:

Be it known that I, RICHARD H. KR LL,

to be removed as an entirety, exposingall of the parts so that they can be readily and thoroughly cleaned.

A further object is to provide a removable ice plate in the bottom of the tank, so

that when" said plate is removed, the drip sheds and drip pan can be thoroughly cleaned without removing the ice tank.

A further object is to provide an improved construction of refrigerator in which allgutters and similar slime collecting passages are done away with, and in lieu of such passages, providing smooth surfaces which can be readily cleaned.

A further object is to provide a refrigerator in which the air is permitted afree circulation so that the articles in the refrigerator may be kept at a low temperature, and permit such a volume of circulation as to keep the air free'andodorless, the opening and shutting of the door being sufficient to supply a sufficient amount of fresh air during use of the refrigerator so as to keep up the necessary circulation, and prevent dead air spaces which are decidedly objectionable.

A. further object is to provide a refrigerator of the character stated which will be extremely simple in construction, comparatively cheap to manufacture and strong and durable in use.

With these and other objects in view, the invention consists in certain novel feat res of construction andcombinations and lirrangements of parts, as will be more fu ly hereinafter described and pointed out in the claims. V

In the accompanying drawings: Figure 1 is a perspective view illustratingmy improved ice tank with its drip sheds and.

drip pan as such parts appear when the tank is removed from the refrigerator. Fig. 2 is a view in cross section through a refrigerator illustrating my improvements in position therein. Fig. 3 is a view in section on the line 33 of Fig. 2, and Fig. 4 is a plan View of the ice plate.

1 represents a refrigerator box Which may be of any ordinary form, and which is provided With'suitable closures (not shown) for the ice and food compartments.

2 represents my lmproved 1ce tank which is preferably, although not essentially, provided with inclined sides 3 and ends 1. The tank is made up of metal and provided at its upper edges with laterally projecting flanges 5, preferably formed by a double thickness of metal as shown, and these flanges are supported upon the wall of the box 1.

Handles 6 are provided. in the tank to permit the same to be readily removed whenever desired, and perforations (preferably two rows) are provided in one side and both ends as shown at 7 to admit air to the top of the tank. The bottom of the tank is provided with an inwardly projecting flange 8 supporting the ice plate 9.

This ice plate is composed of'a corrugated sheet of metal strengthened. by longitudinal bars 10 secured to the lower face of the plate and at right angles to the corrugations, so that while the corrugations strengthen the plate in one direction, the bars strengthen the same in the other direction and permit the necessary amount of ice to be readily supported in the tank.

Depending bars 11 and 12 are secured to the sides of tank 3, and project below the tank as clearly shown. The bars 11 and 12, at both sides, support drip sheds 13, and the .plate 9 above said drip sheds is perforated as shown at 14 to allow the air and the drip from the'iceto pass through onto the sheds 13. The inner bars 12 are provided at their lower edgeswith inwardly projecting wire tracks 15 which support a drip pan 16 and into this drip pan, the sheds 13 direct the water.

As seen clearlyin Fig. 3, the drip sheds 13 are at an angle or incline, and at their outer ends extend beyond the ends of tank 3, so

that any water which forms on the outer.

face ofthe tank by reason of condensation is directed into the water sheds and not into the food compartment. To further catch any condensation, an upwardly projecting lip 19 is provided on the outer edge of each drip shed. The wire tracks 15, above referred to, are so positioned that the drip pan 16 can be readily slid into and out of place, supporting the drip pan throughout its movement, and while said tracks are in a general horizontal position, they are slightly inclined to allow the water to drain to one end of the pan where it passes through a nipple 17 into adrain pipe 18.

In operation, the air circulates from the lower portion of the refrigerator around the outside of the tank 1, through the perforations 7 thence down around the ice, through the perforations .14 in ice plate 9, and thence down around the drip sheds and drip pan into the food compartment. This circulation is maintained so that the air is constantly being cooled, and as the door of the refrigerator is necessarily opened from time to time, a sufficient amount of fresh air is admitted thereby to maintain the proper circulation. WVith my improvements, the water passes over smooth surfaces, so that such smooth surfaces, namely, the ice pan, the drip sheds, and the drip pan, can be readily cleaned by wiping or scrubbing their surfaces, and any slime which accumulates can be readily removed. Furthermore, with my improvements the tank with the drip sheds and the pan can be'readily lifted out of the refrigerator, so that all ,parts are ex-' posed and can be easily cleaned, hence the refrigerator is a sanitary one and can be kept in perfect condition by any one of average i intelligence. 3 5

Various slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes andalterations as fairly fall within the spifit and scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. a In a refrigerator, the combination with a box, of an ice tank supported in the box and spaced from the walls thereof, of two drip sheds located below the end portions of the tank extending beyond the ends of the tank, an ice supporting plate in the tank having openings in its end portions draining into the sheds, said sheds inclining downwardy toward their inner ends, and a removable drip pan supportedin a lower plane than the Water sheds and into which both water sheds discharge, substantially as described.

ends of the tank, said drip sheds. inclining downwardly toward their inner ends, an ice plate supported on the flanged bottom of the tank and having perforations therein above the sheds, tracks secured to certain of said depending bars, and a drip panremovably supported on the tracks and located in a lower plane than the drip sheds with the inner ends of the drip sheds discharging into the drip pan, substantially as described.

, In testimony whereofI have signed my name to this specification in the presence of two'subscribing witnesses.

I RICHARD H. KRALL.
